No, past strep does not "change" or "activate" into scarlet fever
, so it's not that. Most likely his facial rash
is an allergic/atopic rash, for which the doctor may recommend non-allergic soothing creams or a course of a single-daily application of mild steroid
cream. His vomiting
could also be due to other causes, so the doctors must investigate further if he continues to vomit the same way. Was a barium swallow imaging study done for him for his vomiting? If not, it may be worthwhile to do this study.
As to his fever, it may be due to a concurrent virus.
